Abstract
This thesis introduces a frequency converter constant pressure water supply system which controlled by the fuzzy controller DB-3000A and the frequency converter INVTG9011T4.The double pump can be controlled by a frequency converter efficiently. The frequency conversion constant pressure water supply system is designed by a operation mechanism which has dual-pump with four status. The pressure of water supply has been decided by the water yield of consumers. The pressure value of pressure gauges decides the degree of working load. This system worked well in practical application. This system has advantages like security in operation, flexibility, electricity saving, extended the life of the pump, and so on.
